Description
Technical Field
Relates to a novel simple air pulse stimulation device for treating dysphagia, which can promote the recovery and reconstruction of deep muscle activity.
Background
Dysphagia refers to the problem of ineffective and safe feeding due to impaired function of the mandible, lips, tongue, soft palate, throat, esophageal sphincter or esophagus. At present, the swallowing disorder is clinically treated by treatment methods such as ice stimulation, acid stimulation, air pulse, electrical stimulation, acupuncture and moxibustion and the like. The ice stimulation mainly comprises the steps that a cotton swab is frozen and then repeatedly penetrates into the oral cavity of a patient for stimulation, on one hand, the cotton swab is mostly acted on superficial muscle groups, and the effect on deep muscle groups is not good; on the other hand, the ice is likely to cause choking after melting. Acid stimulation is mainly to stimulate taste buds, and the used substances such as dark plum powder can cause side effects such as gastrorrhagia and is not suitable for patients with diabetes and chronic gastropathy. The electrical stimulation is to stimulate structurally intact lower motor neurons with low frequency current to activate or cause muscle contraction to improve muscle function or to treat neuromuscular disorders. The nerve and muscle of the throat are electrically stimulated by inputting low-frequency pulse current, so that the nerve and the deglutition muscle group are excited, and the recovery and reconstruction of the deglutition reflex arc are promoted.
